Principles
stress is the force you apply, strain is the respond moduli is ???
There is a lot of plastic you can use, the recommended are HDPE, Delrin (a little bit of elesticity), Aluminium (speed and feeds are lower) using trocoidal? toolpath (circles)
Tslots for beams
pick
- material
- join system
- frame system
Jens cycloid gear
othermill there is a “hole” aroud one shaft spalling when 2 pieces of same material rub together (friction)
sleeve bearing (selflubricant ?)
Delrin on aluminium is a law friction motion
mechanisms
linkages: whippletree pantograph Sarrus (to flex/bend materiel, linear motion axis)
